Supported email formats

A valid email address consists of a prefix (local-part) and a domain.

The prefix (local-part) appears to the left of the @ symbol and the domain appears to the right of the @ symbol.

For example, in the email [e-mail] ‘local-part’ is the email prefix and ‘domain.com’ is the email domain

The domain may consist of one or more labels separated by a . (dot) - [e-mail] - where each domain label can have a maximum length of 63 characters.
